Activision has kicked off five-day double XP periods for the two most recent Call of Duty games, 2013's Ghosts and 2012's Black Ops II. Beginning today and running through Friday, which is Halloween, players will earn double XP in every match they play in either game.

"This will be the first time you've ever looked forward to a Monday," Black Ops II developer Treyarch wrote on Twitter. Meanwhile, Ghosts developer Infinity Ward asks: "Time to get that last prestige?"
